Hi,
How can I split the below assembly line using define_split RTL template
<1> rd = dps
into the below two liens
<2>
rd = dps
rd = signext(rdhl)
Here rd is 40-bit register
dps is 32-bit register contains the address
Here register name can be r1, r2 ... rd. and
dp1, dp2, .....dps
sigext(rdhl) is the sign extending from 32-bit to 40bit.
Regards
Raja
